US Vice President Mike Pence won't eat alone with women who aren't his 'mother'

The US Vice President's eating habits have caused a huge debate online overnight.

Evangelical Christian Mike Pence apparently refuses to dine alone with any woman who isn't his wife (and closest advisor), Karen. He also reportedly calls the Second Lady, 'Mother' — and has had a red phone installed in his office which provides a direct line to her.

The Washington Post uncovered this information while researching a profile piece on his wife. Pence had previously spoken about his dinner rule in a 2002 interview with The Hill, while Rolling Stone had previously reported the nickname which was overheard by a staffer at a dinner party.

In the interview with The Hill, Pence also said he doesn't drink alcohol at events when Karen is not in attendance. And since The Washington Post unearthed the revelations, they have sparked a huge debate online about the pros and cons of Pence's life choice.

Pence, who is a vocal pro-life advocate and has supported policies to limit LGBTI rights, says he avoids eating with other women out of respect for his marriage. He also says his evangelical faith advises against it.

Many have called Trump's Vice-President out for sexism, saying his reasoning is based on outdated Christian teachings that portray women as temptresses.

Others believe his personal policy limits the interactions he has with women, and therefore could prevent female reporters, advisors and politicians from being given the same opportunities as their male counterparts.

But, some have defended his decision, asking if there's ever an appropriate reason for a male and a female who aren't family to go out to dinner together.

Pence's code could also be illegal under discrimination laws. The Atlantic published a report two years ago looking in to other male members of Congress who have the same policy.

"So much happens in creating trustful relationships and if you can’t develop a trustful relationship where you’re having some one-on-one time, as the men apparently are getting — I can see many reasons why this is a terrible idea, terrible in the sense of discriminatory", employment discrimination lawyer, Debra S. Katz said at the time.
